The best review of this book series was my grandson Joey's comment. "I read all three books in one week!" This despite the lure of his video games and his two brothers. Joey is ten. When finished, his brother Peter eagerly began his turn to read the books.
Author K.M.Doherty has done an amazing job crafting a story filled with science, fantasy, and all the action kids love.
